Mortar layer

ABSTRACT

A mortar layer for laying a viscous mortar of a uniform width and thickness on a surface is disclosed. The variability of the thickness and width of the mortar is also permitted by adjustment of various components of the mortar layer. Uniformity in deposition of the mortar is insured by an agitator mechanism shaking the mortar onto the surface.

1 35 2 E I 33 ,4 r 35 7 MORTAR LAYER This invention relates to a device for laying mortar.

In the construction industry the mode of laying mortar on concrete blocks or bricks during the construction of a wall or the like has not appreciably changed over the decades and centuries. for a trowel has been used to convey mortar onto the block or brick and to spread the same over the surface thereof so that another block may be layed supcradjacently thereon as those common in the art will know.

With increasing labor costs and labor contents costs of construction have increased.

It is an object of the invention to provide a carriage device for laying mortar on the surface of the blocks which are interlacingly layed into blocks and the like.

It is another object of the invention to provide a device for laying a uniform width and thickness of viscous mortar onto a surface.

The invention therefore contemplates a mortar layer for laying viscous mortar of a uniform width and thickness onto a surface comprising a body disposing an internal chamber having an upper viscous mortar storage region and a contiguous depending leg region extending into a terminal opening. an agitator disposed within the chamber and extending into the contiguous depending leg region for shaking the viscous mortar therein. means to activate the agitation, and means for moving the body along the surface and to constrain the terminal opening at a predetermined distance from the surface such that viscous mortar of uniform thickness and width is deposited onto the surface as the layer passes over it.

The invention will now be described by way ofexample with reference to the accompanying drawings in which:

FIG. I is a perspective of the embodiment of the invention.

FIG. 2 is a section along lines Il-ll of FIG. 1.

FIG. 3 is a perspective of the embodiment of FIG. 1 in use on a row of bricks.

Referring to FIG. I a mortar layer 10 includes a body 11 mounted on four adjustable wheels 12. Preferably the body 11 has a post-step slot arrangement I4 at each corner to carry the axis of each wheel 12 and to adjustably place the wheel at predetermined positions relative to the base so as to carry the body at different selectable heights from a running surface. The body I] displays an internal chamber of two marginal depending legs 17 having lower terminal openings 18. The upper portion of the legs respectively communicate across the crotch into an upper unitary contiguous storage region I9. A vertically movable agitating member 21 in the shape of an inverted V and in the vicinity of the storage region 19. extends over the crotch and down along the internal portions of the legs 17 as more particularly seen in FIG. 2. Along the outer margin of each of the depending legs extends a second movable member 22. Each of these movable members 21 and 22 are attached to a horizontal bar 23 which is linked by a projecting loop straps 24 to respective throw-arms 26 of a rotatable crankshaft 27 which straddles over the top of the body I I and extends outward from the body to dispose tips of the crankshaft 27 away from the body. Onto these projecting tips of the crankshaft 27 can be affixed at crankshaft 28 on either side of the body 11. The crankshaft 27 is rotatably secured to the upper part of the body through appropriate bushing members 31.

Along the rear margin of each leg region 17 is slot 30 and adjustable closing gate 31. The slot 30 communicates into the leg regions and permits. as the layer is moved over a running surface. such as the row of bricks 36 of FIG. 3, mortar 39 to be deposited in the running surface 37, in two streams 40 along the margins of the row. Further. adjustable curbs 33 and 34 are provided along the lateral sides of the leg regions I7 near the lower terminal opening 18. The curbs 33 are adjustably secured to the margin by the thumb screws 35. The dis tance between lower edge of the curbs 33 and 34 relative to the running surface 37 will determine how wide a stream of mortar can be layed.

In operation, referring to FIG. 3, the layer 10 is set on a row of blocks 36 such that the wheels 12 straddle the margins of the blocks 36. The layer is propelled by hand against one of the carrying handles 29 and the viscous mortar 39 within the storage region 19 is conveyed through the legs and terminal openings onto the block as two continuous uniform streams of viscous mortar 40. In order to assist the deposition of the viscous mortar from the storage region 29 the other hand of a person is used to rotate the crank 28 and to cause the members 21 and 22 to vertically reciprocate vibrating the mortar 39 temporarily enhancing its viscosity and ability to move through the legs 17 to the terminal openings 18 at the base of the body 11. The thickness of the mortar 40 deposited on the bricks is dependent in part upon the slump of the mortar as well as the vertical displacement of the body 11 above the surface of the bricks and the speed of rotation of the crank 27. After some experience a user will know the parameters required in order to provide uniform deposition of visi cous mortar onto a laying surface. Additional control of the uniformity in thickness and width of the deposition of the uniform viscous mortar 39 can be obtained by varying the wheels 12 in their respective slot arrangement 14 or by changing the position of gates 31 to open or close the slots 30 or both; alternatively, the curbs 33 and 34 can be raised or lowered.
